I haven't yet received my MX-500 should be here tomorrow but I have been following this progress since I first started looking at a replacement unit for my home system. I too would say kudos and great work, and if you haven't already I would be aproaching HTM to sell this, and even if you don't go that route I will be following this story as I am definitely interested in any version of this Beta, 2nd generation released or not, keep up the great work.
